All 1 Known Issues
On the 2021-2025 Cadillac Escalade, the 5th generation Escalade (2021+) uses the GM 10L80 10-speed automatic transmission. While improved over the 8L90, some owners report harsh shifting, shudder at light throttle, and delayed shifts. The 10-speed has numerous clutch packs and a complex valve body with frequent adaptive learning resets needed. Some units develop torque converter shudder similar to the 8L90 issue. GM has released multiple TCM software updates to address shift quality. The issue is less prevalent than the 8L90 but still documented.
Common Symptoms
- Harsh or clunky shifts, especially 1-2 and 3-4
- Shudder at light throttle cruising
- Delayed downshift response
- Hunting between gears on hills
- Transmission feels "confused" in stop-and-go traffic
How to Fix
First step is a TCM (Transmission Control Module) recalibration at the dealer - GM has released multiple software updates. A full transmission fluid exchange with the correct Mobil 1 LV ATF HP fluid can help. For persistent shudder, torque converter inspection/replacement may be needed. Some owners report improved shift quality after the transmission "learns" their driving style over 500+ miles after a reset.
What Owners Are Using
Parts and tips from 0+ owners who fixed this issue
- TipGM TSB 22-NA-080 covers 10L80 TCC shudder - fix is TCM recalibration plus full Mobil 1 Synthetic LV ATF HP exchange. Use ONLY the blue-label fluid (GM part 19417577, NOT older 19354121). GM uses 17-20 quarts for machine exchange - insist on full volume
- UpgradeMobil 1 Synthetic LV ATF HP (GM 19417577) is the only authorized fluid for 10L80 shudder fix. 10-12 quarts minimum for pan-drop service, 17-20 for full machine exchange. Full machine exchange has significantly higher success rate. Change every 50,000 miles despite 'sealed for life' claim (GM #19417577)
- NoteIf fluid + TCM fix fails within 500 miles, torque converter clutch lining is worn through. Updated torque converter (GM 24288828) must be replaced. Delaying allows clutch debris to contaminate valve body, escalating $1,200 converter job into $4,000+ transmission rebuild.
